The first filter structure 2021 is used for performing preliminary filtering on the gas generated by the tobacco block 201, gas after preliminary filtering flows into the second filter structure 2022 through the gas guide hole 203, and then the gas is finally filtered by the second filter structure 2022 before being sucked by the user.

In some embodiments, a gas passage rate of the first filter structure 2021 is greater than a gas passage rate of the second filter structure 2022, that is to say, the first filter structure 2021 has a lower filtration degree for gas, while the second filter structure 2022 has a higher filtration degree for gas. For example, a density degree of a filter structure of the first filter structure 2021 is less than a density degree of a filter structure of the second filter structure 2022. For example, an average size of internal pores of the first filter structure 2021 is greater than an average size of internal pores of the second filter structure 2022. In some embodiments, one of the first filter structure 2021 and the second filter structure 2022 is used for physical filtration, while the other of the first filter structure 2021 and the second filter structure 2022 is used for chemical filtration. For example, the first filter structure 2021 has an electrostatic layer or a sponge-like porous structure layer that can prevent specific particles from passing through in an electrostatic adsorption or sieving manner, while the second filter structure 2022 contains specific substances that can generate neutralization with harmful substances.

This embodiment adopts the solution that the electronic assembly 2 is heated but not combusted, thereby avoiding jeopardizing human health caused by harmful substance tar that may be produced in a combustion process.
